Usage: #{$0} [options]
Utility for obtaining a Fog vCloud Director session token. It will output a
shell `export` command that can be consumed with:
eval $(FOG_CREDENTIAL=example #{$0})
It requires a Fog credentials file (e.g. `~/.fog`) with the host and user
set, but the password set to an empty string. The password can either be
entered interactively or piped in, for example from an environment variable:
printenv PASSWORD_VAR | FOG_CREDENTIAL=example #{$0}
